Stock sound amplified and similar, but better look: Nismo
More exotic sound, true dual, nice look for the back: Greddy Evo2
HKS Ti dual if you have quite something to spend, but not worth the money IMO.
It's all very personal, as in combination with test pipes/high flow casts an exhaust can sound completely different. The best is to meet up with someone who already has a aftermarket exhaust installed.
And yes, the choice would probably must different if you go for FI.
